Could you provide the following information:
- version of OpenDaylight you're using
- some logs, or at least a stacktrace

While the device is connecting, OpenDaylight tried to establish the schema context, based on the advertised capabilities from the hello message. The schema context will be containing specified sources, pulling in any dependencies they may have.
"No more sources for schema context" means while trying to setup the SchemaContext of the device, it never succeeded to accomplish it, exhausting all the specified sources, hence failed to create the schema context, thus fail the connection.
